UUUULABL'QOM.

To all whom 'it may concern:

Be it known that I, CHARLES TmBoDEAU, a citizen of the United States,residing at Chelsea, in the county of Suffolk and State ofMassachusetts, have invented new and useful Im rovements in CircularLooms, of which t e followin is a specification.

My invention re ates to improvements in circular looms, and the objectof my invention is to simplify the a paratus now in use for this purposeand r uce the cost of production.

My invention primarily consists in construeting a loom with a shuttleprovided with a nose located below the normal plane of the warp threads,so that it will readily pass under the same when in their normal plane,and also providing in said loom' a series of rotatingl arms 4arranged todepress alternate or ot er predetermined warp threads below the noseofsaid shuttle, in order that the weft thread carried byl said shuttlewill be properlg/fllaid between the Warp threads.

y invention further consists in the novel features hereinafter fullydescribed and claimed.

Reference is hereby made to the accompanying drawing in which similarnumerals of designation refer to similar parts throughout the severalviews.

Figure 1 is a front elevation of my machine showing the central portionthereof in vertical section. Fig. 2 is a plan View of my machine showingthe cop-ring, cops, shuttles, race-way and switch. Fig. 3 is an enlargedplan view of one of the shuttles showing its obbin, thread guide, and suporting rolls. Fig. 4 is an enlarged View in efevation of the shuttledriver and device for depressing the warp threads, and portions of twoadjacent shuttles showing the interval between. Fig. 5 is a View ofcertain of the )arts illustrated in Fig. 4, showing the nose o one ofthe shuttles about to pass over one of the warp threads, and showing theposition of one of the depressing arms at the time this is accomplished.Fig. 6 is a section on line 6-'-6 of Fig. 3, showingr in elevation thecops, rolls and adjacent parts. Fig. 7 is a view in elevation showing 1ndetail the feed rolls and gearing for operating the same. Fig. 8 is aplan View of one of the shuttle rolls showing means for the eccentricadjustment of the same.

Referring to the drawing, 9 represents the legs of my machine which areconnected by Speciflcation o! Letters Patent.

R eferring;r to 1 and 2, the operation of my machine is as follower-'Pheulley 3S is connected ith the drivingr belli, und the shaft 20 thereby-n-used to rotate. The movement of said shaft is communicated throughthe gears 25, 24, te the revoiving sleeve 123 carrying the shefts 10. Byrevolvintjr seid sleeve the shaft carrying the shuttle driver and roterydepressor is mused to rotate. The shuttles ere thus started in motionend ere drivenrn their circuler path shout the work. 'lhe position ofthe werp threads u., c, d, e, endj, und their relation to the neitthreads is shown in Fig. 3, where the weft thi-ends g tre seen to pnssover und under alternate nur threads. As the shuttle is driven lowfnrrl(see Figs. 4 :ind 5) the urp threztd c shown in engagement vcith the topof the shuttle :tt th(` right passes :dong: the saune to the inelinedsnlfatee 100 und there fzills into the slot 108 ut the extremity o1'Vone of the depressing urnis 70, it heiner timed to engage sind threud utthis point.

Further preeeedilu,r the sztid werp threinl, stillhome in the slot o1' sind depressing itrm 71, is de n'essed in seidgroove 102 hy seid erin 71 below the nose of the shuttle ns shown inFig. 5, end is held in this position until enguged by the bottom surfaceof seid.` shuttle und is released from the slot 108. When the shuttlehns pr'oeeeded 4on its path snlleiently, the thread c will occupy theposition showlrby threud d, (see Fi 4) and will rise into the recess 113from w ience it passes along the base of the nger 112 behind the toe107, and occupies a position above the nose 111 of the succeedingshuttle, which shuttle engages on its upper surface with said thread,and causes 1t to occupy the position shown by thread f. The feed rolls62a and 62b are so timed as to gradually feed the completed product tothe oor below, and are operated by the sprocket gears and chain shownconnected to shaft 66, which is in turn operated by gearing andsha'r'ting connecting the same to the main shaft as above described.
